Using an entirely new game engine created by the Las Vegas-based developer Petroglyph, the game will feature beautifully rendered land and space battles set on memorable planets such as Hoth, Tatooine and Dagobah as well as never-before-seen environments taken directly from the Star Wars films and expanded universe novels. In the game, players can choose to join either the Rebel Alliance or the Galactic Empire, building and setting up tactical forces that can be unleashed on the enemy in real-time 3D. All of the gameplay and action within Star Wars: Empire at War is a persistent, meaning that strategic and tactical elements from previous events will have a permanent effect on the galaxy.
